Fans of Jessie J, worry not - the "Masterpiece" singer will still be belting out her high notes live for quite some time. Despite rumors that her heart condition, Wolff-Parkinson-White syn­­drome, may cause her to cease singing live, J herself has dismissed the stories in papers like The Sun and The Mirror as pure hogwash.

The Mirror initially reported that J may soon have to resort to mimicking her hits like "Domino" and "Bang Bang" live if her health did not improve. According to a source, J said that, "I have prided myself in having got this far without having to lip-sync but if my career carries on moving at the pace that it is, I will have to lip-sync to be able to stay well. My songs are so big."

The news that J's future live career may be in jeopardy followed her Australian tour cancellation earlier this month, due to an illness unrelated to her heart condition.

But, J is putting all those rumors to rest. In a post on her Instagram, the 26-year-old singer acknowledged that she had a heart condition (and that she's known her whole life!) but that it won't affect her career anytime soon.

"I still have a heart problem | Dun dun dun | Papers acting like I didn't know lol | Had it since I was born | But my heart is ok | My body is healing | I don't have to mime to hit my high notes on stage | Who believed it? Fess up! | Made me laugh because it was so choopid | Don't even know where they get these stories from | Maybe from Source and his best mate bullsh*t," she wrote.

J also said that she is still recovering from the illness that caused her to can her Australian tour, but she's getting better thanks to her mama, Homeland and Tim Tams.

 Facts | Feelings | Random things I am ok | I'm feeling better | I was really unwell | I have slept a lot | I have watched every series of Homeland in bed | I'm addicted to tim tams | I still have a heart problem | Dun dun dun | Papers acting like I didn't know lol | Had it since I was born | But my heart is ok | My body is healing | I don't have to mime to hit my high notes on stage | Who believed it? Fess up! | Made me laugh because it was so choopid | Don't even know where they get these stories from | Maybe from Source and his best mate bullshit | anyway | My Mum flew to Australia to be with me | I love my Mum | She has cooked for me everyday | And held my hand whilst I've been in pain | Im sorry for all the fans I let down | I f***ing hate that my mind is stronger than my body sometimes | I didn't want to cancel shows but a doc told me I had to | I cried a lot | I had to listen | Thank you for all your well wishes | I need them | If I could hug every sick person right now I would | Rest and be well | Luke is the love of my life | I'm using these |'s because he uses them and I miss him | Off to bed | *Adlibs* | I just walked into a spider web.... | I want a Tim tam...
